The proposed bill establishes regulations regarding the length of trains operating within the state of Washington, aiming to enhance public safety and environmental protection. It defines a maximum train length of 7,500 feet, with exceptions allowed only through approval from the Washington Utilities and Transportation Commission. The bill highlights the safety risks associated with excessively long trains, particularly in Washington's diverse geographical terrain, and emphasizes the state's responsibility to ensure safe railroad operations.

Penalties for non-compliance are outlined, with fines starting at $25,000 for the first offense and escalating for subsequent violations. The commission is granted the authority to authorize exceptions for certain trains under specific conditions, including the requirement for additional crew members to ensure safe operation. The bill also includes provisions for the enforcement of these regulations and addresses the validity of its provisions, ensuring that if any part is deemed invalid, the remainder of the act remains effective.
